GENERAL DESCRIPTION
The M12L32162A is 33,554,432 bits synchronous high
data rate Dynamic RAM organized as 2 x 1,048,576 words
by 16 bits, fabricated with high performance CMOS
technology. Synchronous design allows precise cycle
control with the use of system clock I/O transactions are
possible on every clock cycle. Range of operating
frequencies, programmable burst length and programmable
latencies allow the same device to be useful for a variety of
high bandwidth, high performance memory system
applications.
